The lens is not used on its own, but in combination with filter(s), camera, scene light conditions etc. etc. Thus one rarely gets data that cover all situations. I consider these "good for [xxx]" compilations a starting point, nothing more. Add your own experiences.
The most generally applicable rule is never to stop down the lens too far, and avoid pointing the lens towards the sun or other bright light sources.Unless, of course, all those artifacts, ghosts, and flare, are considered to be the central idea of the envisioning and creative process.
